Abstract
Techniques are disclosed to provide a reference signal via a switched capacitor filter for image detector arrays in accordance with one or more embodiments. For an example embodiment, a method of providing a sampled and filtered reference signal to an image detector array includes receiving a reference signal; sampling the reference signal with a first capacitor to store a sampled reference signal based on the reference signal; coupling a second capacitor to the first capacitor to share charge stored on the first and second capacitors to generate the sampled and filtered reference signal to store on the second capacitor; and decoupling the second capacitor from the first capacitor, wherein the sampled and filtered reference signal is stored on the second capacitor to provide for one or more image detectors within the image detector array.
